obsolete front page displayed

[RobKushler]

On my website, healingeducation.org, the front page permalink brings up an obsolete version of the home page, and causes an obsolete version of the main menu to appear. Clicking on another page in the menu fixes the menu, but returning to the home page unfixes it. I have reassigned the Unyson front page to a new, different version of the home page, but the obsolete version keeps displaying.

In the correct menu, the selection Training Programs -> Pop-Ups takes you to healingeducation.org/pop-up which is the correct version of the page. In the "bad" menu, the same selection takes you to healingeducation.org/pop-ups which is an obsolete (and seriously messed up) version of the page. The "pop-ups" slug is not used on any current pages on the site, but this "ghost page" apparently still exists somewhere. This is not a caching problem - all caches were emptied, and the problem also shows up in private windows. Are there entries in an SQL table somewhere that must be removed?

More generally, are the problems with the latest upgrade of Wordpress and php ever going to be fixed?

Well, the menu/page display problem has gone away. I tried creating another version of the home page (not using Unyson). When I assigned it as the home page (in settings -> reading), the site started using the "good" version created earlier and the menu no longer gets corrupted when the home page is visited. Sigh ...

Still wondering whether Unyson is going to be updated.
